Question

How do I send a cross-domain POST request via JavaScript?

Notes - it shouldn\'t refresh the page, and I need to grab and parse the response afterwards.

One more important thing to note!!! In example above it's described how to use

$.ajax({
    type     : 'POST',
    dataType : 'json', 
    url      : 'another-remote-server',
    ...
});

JQuery 1.6 and lower has a bug with cross-domain XHR. According to Firebug no requests except OPTIONS were sent. No POST. At all.

Spent 5 hours testing/tuning my code. Adding a lot of headers on the remote server (script). Without any effect. But later, I've updated JQuery lib to 1.6.4, and everything works like a charm.
